Cannot run the sample virl labs

jomar_alexis41 — Fri, 27 Sep 2019 10:01:45 GMT

Hi DevNet,

I am having problem to connect on this issue below.

How would i know if the IP is correct?

I just follow the this link https://blogs.cisco.com/developer/virl-up-netdevops-network-simulation.

Can you advise me what is the issue?

$ virl up virlfiles/2-ios-router

Pulling from virlfiles/2-ios-router

Saved topology as topology.virl

Creating default environment from topology.virl

Exception raised while running your command

Please open an issue and provide this info:

I was not able to replicate this, i would advise to cancel the reservation and create a new one. There appeared to be an issue with the reservation for you sadly.

Jomar, it looks like you are doing this on your local machine and not the devnet sandbox devbox/jumphost. Unless you have fully installed virl and all the required tools this will error (as you are seeing). Please check the instructions in the sandbox how to connect to the devbox/jumphost.

Hope this helps.
